The cosmic infrared background (CIB) spans a wide range of redshifts. Its measurements are thus a powerful tool to map the star formation at high redshifts and connect the host dark matter halos with the galaxies residing in them. Also, in cross-correlation with the cosmic microwave background (CMB), CIB acts as a cosmological observable to detect the dark energy. Despite being an excellent astrophysical and cosmological probe, CIB acts as a foreground for the CMB and line intensity mapping studies. In this talk, I will explore both these sides and discuss the possibilities to convert the CIB from a foreground to a signal.
